                  use a <a href="https://cdnjs.com/libraries/Chart.js" target="_blank">Chart.js CDN</a>. Detailed

                <p>It&apos;s easy to get started with Chart.js. All that&apos;s required is the script included in your
                  page along with a single <code>&lt;canvas&gt;</code> node to render the chart.</p>
                <p>In this example, we create a bar chart for a single dataset and render that in our page. You can see
                  all the ways to use Chart.js in the <a href="getting-started/usage.html">usage documentation</a></p>
